Description
Technical field
The present invention relates to a kind of ventilation unit that is used for the high pressure electrical functional units.
Background technology
At the high pressure electrical functional units for example in the course of normal operation of switching device (switchgear), the used heat that electrical functional units produced discharges to the external world by metal framework, under the situation of electrical functional units generation internal fault, when for example in medium-voltage equipment, electric arc occurring, discharge by identical metal framework and the parallel pressure releasing plate of opening by the compressed air that electric arc produces.
Because the structure of switching device is relatively compact, the exhaust port area of high pressure electrical functional units through being usually used in having the pressure relief area of people's process and being used for the metal framework of release heat.
But such structure exists not enough, and when occurring for example being raise by the such fault build-up of pressure of the electric arc in the electrical functional units, the part high-pressure hot gas also can outwards discharge by metal framework, thereby might jeopardize the people of outside.
Summary of the invention
Thus, the objective of the invention is ventilation to be provided and to provide highly protection to the hot gas that discharges from electrical functional units under the high pressure to the high pressure electrical functional units.
This target realizes by a kind of ventilation unit of high pressure electrical functional units, described device has at least one and is used for the passing away that exhaust is flow through, it is positioned at the electrical functional units outside, the gas that electrical functional units is discharged has step-down and/or cooling effect, and at least one in described at least one passing away has at least one inlet, it can be connected with at least one outlet that is positioned at the electrical functional units upper-side area to receive exhaust, and at least one in wherein said at least one passing away is along the downward extension of the dorsal part of electrical functional units and comprise an exhaust outlet in underside area.
For example, by at least one electric component in the electrical functional units for example power switch and/or current/voltage converter and/or bus bar and/or press in other and/or used heat that the high-voltage electrical apparatus parts produce from electrical functional units, can be discharged in the external environment condition of electrical functional units through at least one passing away that links to each other by at least one outlet of at least one electrical functional units, the hot gas that described at least one passing away is set to cool off and/or step-down is discharged can be discharged by at least one exhaust outlet of described at least one passing away from the gas of cooling and/or step-down.
Electrical functional units other parts except described at least one outlet may all be sealed, and therefore, for example, hot gas must be discharged by described at least one passing away.Electrical functional units also may for example have a plurality of closable openings, open in normal operation and in environment, discharge used heat, but these closable openings are closed under the situation that high pressure increases, but, hot gas for example can use baffle plate, so that can not further be discharged by these closable openings when breaking down.
Because at least one in described at least one passing away can be connected with at least one outlet that is positioned at the electrical functional units upper-side area and be used for receiving exhaust, for example used heat can pass by at least one passing away from electrical functional units by heat free convection and discharge.Therefore, for example, the accumulation of heat in the time of can avoiding the electrical functional units normal running just not have fault.
Described at least one passing away can by Heat Conduction Material for example for example sheet metal make, hot gas can controllably discharge to the external environment of electrical functional units by described at least one passing away when flowing through described at least one passing away like this, that is to say, can and/or be cooled by step-down, meanwhile but not entail dangers to the people.Other suitable materials also can be used for making described at least one passing away.Therefore, for example, suddenly a large amount of heats that produce in electrical functional units can partly slowly be discharged in the environment by the surface of described at least one passing away with controllable mode, and the heat of other parts for example can discharge by at least one exhaust outlet of described at least one passing away.
In addition, can adjust by the length and/or the cross-sectional area of for example described at least one passing away of some parameters, and therefore adapt to the state of electrical functional units by cooling effect and/or antihypertensive effect that described at least one passing away brings.Therefore, for example, described at least one passing away can have minimum length, and the length of electrical functional units side for example can be guaranteed the abundant cooling and/or the buffering effect of exhaust like this.
Therefore, the advantage that has according to device of the present invention is: for example, when the such fault of electric arc for example takes place in electrical functional units, generate hot gas and can directly not be discharged to the environment from what at least one outlet of described electrical functional units was discharged by at least one opening of described electrical functional units, but at first introduce at least one passing away be positioned at the described electrical functional units outside, by the hot gas after described at least one passing away cooling and/or the step-down and also only be cooled and/or step-down after just can be discharged in the environment by at least one exhaust outlet of described at least one passing away.Therefore, jeopardize the people of electrical functional units outside in the time of can avoiding in electrical functional units, breaking down.
Because at least one dorsal part along electrical functional units in described at least one passing away extends downwards, at least one exhaust outlet of described at least one passing away can be arranged in the lower area of the dorsal part of electrical functional units for example, so particularly is positioned at the electrical functional units outrunner and can reaches high security.
Therefore, the hot gas of discharging from electrical functional units not only can also can also be deflected to the electrical functional units dorsal part by step-down and/or cooling, is positioned at the electrical functional units outrunner thereby can avoid especially jeopardizing.
The ventilation unit of electrical functional units for example can directly install and fix on electrical functional units, but perhaps as an assembling parts (just can connect) on electrical functional units and dismountable parts can be installed just.For example, this device can by fixed part for example screw be connected to electrical functional units.
In a kind of design of the present invention, extend at least one outside to small part along electrical functional units of at least one in described at least one passing away.
Therefore, described at least one passing away can be at least partially disposed at least one outside of described electrical functional units, can become space-saving attached of this device thus.For example, described at least one passing away can extend to the dorsal part of electrical functional units from the top side of electrical functional units.
In a kind of design of the present invention, at least one in described at least one passing away has at least one sweep.
For example, this sweep of described at least one passing away can be that arc-shaped bend also can be a sharp bend.
Therefore, for example, at least one passing away of described electrical functional units top side can link to each other with at least one outlet of electrical functional units, described at least one passing away can extend in the top side of electrical functional units, have a bent angle and/or sweep then, and then transfer extension downwards on the dorsal part of electrical functional units to, thereby, for example, at least one exhaust outlet of described at least one passing away can be positioned at the lower area of described electrical functional units dorsal part.
Therefore, produce when for example in electrical functional units, breaking down electric arc for example and for example can introduce the described at least one exemplary passing away that originates in the electrical functional units top side from the hot gas that at least one opening of described electrical functional units is discharged, be cooled and/or step-down, sweep by described at least one passing away turns to and then is guided through the passing away that extends downwards on electrical functional units rear side back then, for example, enter the lower area of electrical functional units dorsal part, this moment, hot gas can be cooled off and/or step-down further.Can assign to realize longer passing away by at least one bend that uses described at least one passing away thus; it is longer that thereby the hot gas of electrical functional units is discharged the route of process; bring better cooling and/or antihypertensive effect thereupon; also just improved protective capability to the electrical functional units outrunner; the height that electrical functional units took up space that particularly is equipped with according to device of the present invention is lower than normal value, during for example less than 2300mm.Avoid injuring the people of electrical functional units outside in the time of can in electrical functional units, breaking down thus.
For example, in described at least one passing away at least one also can have a plurality of sweeps and in the top side of electrical functional units and/or dorsal part extend, the length of described thus at least one passing away can further extend, thereby reaches better step-down and/or cooling effect to discharging gas.

The specific embodiment
In the preamble for example all explanations and the advantage thereof about the various different designs of the present invention also all be applicable to the embodiment shown in the accompanying drawing.
Fig. 1 shows the schematic diagram of first embodiment of the ventilation unit 100 of electrical functional units 110.
In institute's drawings attached, similarly parts are with identical numeral, therefore, also are applicable to like in other embodiments in the same manner about the introduction of for example its structures of parts and advantage aspect in a kind of embodiment.
Electrical functional units 110 can be to press and/or high-tension switch gear in for example, or transformer unit, or pressure and/or high voltage component in other, can pass or impenetrable functional unit.
The embodiment of device 100 shown in Figure 1 only shows a passing away 101 as example, and it is arranged on electrical functional units 110 outsides and the gas of discharging from electrical functional units 110 is had step-down and/or cooling effect.But device 100 also can be provided with many and be used for step-down and/or cool off the passing away of discharging gases from electrical functional units 110.
Described at least one passing away 101 can be connected at least one outlet 115 of electrical functional units 110.This at least one outlet 115 can be positioned at for example top side of electrical functional units 110, as shown in Figure 1, perhaps also can be positioned at other zones of a certain sidewall of electrical functional units 110.
For example, used heat from electrical functional units 110, it is for example pressed in power switch and/or current/voltage converter and/or bus bar and/or other by at least one electric component in the electrical functional units for example 110 and/or the high-voltage electrical apparatus parts produce, and can be discharged in the external environment condition of electrical functional units 110 through at least one passing aways 101 that connect by at least one outlet 115 of electrical functional units 110.Therefore the hot gas that described at least one passing away 101 is set to cool off and/or step-down is discharged discharge by at least one exhaust outlet 105 of described at least one passing away 101 through the gas of supercooling and/or step-down.
Described at least one passing away 101 can be set to for this purpose by Heat Conduction Material for example metallic plate make, thereby the hot gas that flows through described at least one passing away 101 can be discharged in the external environment condition of described electrical functional units 110 by described at least one passing away 101 with controllable mode, that is to say, hot gas is by step-down and/or cooling, entail dangers to is to the people, and for example cross-sectional area of the Heat Conduction Material that antihypertensive effect can be by selecting to be used to make described at least one passing away and/or length and/or shape are adjusted.Other suitable materials also can be used to make described at least one passing away 101.Therefore, a large amount of suddenly heats that produce can partly be discharged in the environment with the surface of controllable mode by described at least one passing away 101 lentamente in the described electrical functional units.
In addition, parameters such as length that can be by for example described at least one passing away and/or cross-sectional area are adjusted the cooling and/or the antihypertensive effect that are produced by described at least one passing away 101, to adapt to the situation of described electrical functional units 110.So described at least one passing away 101 can have minimum length, for example is the side length of described electrical functional units 110, to guarantee to cool off fully and/or gas is discharged in step-down.
Therefore the hot gas that the advantage that demonstrates according to device of the present invention is to discharge from least one opening 115 of electrical functional units 110 (for example hot gas that produces when electrical functional units 110 breaks down electric arc for example) not at least one opening 115 by electrical functional units 110 is directly released into the environment, but at first by being positioned at described at least one passing away 101 of electrical functional units outside, hot gas is through described at least one passing away 101 cooling and/or step-downs, and only be cooled and/or step-down after be discharged in the environment by described at least one exhaust outlet 105 again.Therefore, can avoid when electrical functional units 110 breaks down, jeopardizing the people who is positioned at electrical functional units 110 outsides.
Because at least one in described at least one passing away can be connected at least one outlet that is used to receive exhaust that is positioned at the electrical functional units upper area, used heat also can for example discharge in the thermal natural convection mode through at least one passing away from described electrical functional units.Therefore, for example, can avoid, accumulation of heat takes place when just not having fault in the electrical functional units normal work period.
For example, described at least one passing away 101 at least one exhaust outlet 105 that can be set to described at least one passing away 101 is positioned at the mode of the dorsal part of electrical functional units 110.Like this, just not only can also additionally can be discharged, thereby can avoid especially injuring be positioned at electrical functional units 110 outrunners by step-down and/or cooling from the dorsal part of electrical functional units 110 from the hot gas that electrical functional units 110 is discharged.
The ventilation unit 100 of electrical functional units 110 for example can directly be fixed on the electrical functional units 110, perhaps becomes (just can connect) to be installed to the electrical functional units 110 and can be from the parts 100 of its dismounting.For example, device 100 can be installed on the electrical functional units 110 by fixed part such as screw.
Fig. 2 shows the schematic diagram of second embodiment of the ventilation unit 100 ' of electrical functional units 110.
Explanation and advantage thereof about first embodiment similarly are applicable to second embodiment shown in Figure 2.
Compare with device 100 shown in Figure 1, the difference of device 100 ' shown in Figure 2 is that its at least one passing away 101 ' has at least one sweep.This sweep can be an arc-shaped bend, that is to say, has the sweep than larger radius of curvature, also can be a sharp bend, as shown in Figure 2.Therefore, described at least one passing away 101 ' can be connected at least one opening 115 of described electrical functional units 110 top sides, for example, described at least one passing away 101 ' extends on the top side of described electrical functional units 110, have a bent angle and/or a sweep subsequently, on the dorsal part of described electrical functional units 110, extend downwards then, thereby, for example, at least one exhaust outlet 105 of at least one passing away 101 ' is located in the lower area of electrical functional units 110 dorsal parts, shown in the embodiment among Fig. 2.
Therefore, the hot gas of discharging from least one opening 115 of electrical functional units 110, the hot gas that when electrical functional units 110 breaks down electric arc for example, produces for example, can at first flow through at least one passing away 101 ' that is positioned at electrical functional units 110 top sides, be cooled and/or step-down at this, sweep by at least one passing away 101 ' changes direction then is downward through the passing away 101 ' that is positioned at electrical functional units 110 dorsal parts and enters for example lower area of electrical functional units 110 dorsal parts then, and hot gas can be further cooled and/or step-down at this.Therefore; make hot gas discharge from electrical functional units 110 along an obviously long path; thereby can reach the purpose of raising to the protection that is positioned at the electrical functional units outrunner; be lower than normal value if particularly be equipped with, during just less than 2300mm according to device of the present invention 100,100 ' the height that electrical functional units took up space.Therefore, avoid injuring the people of electrical functional units outside in the time of can in electrical functional units 110, breaking down.
In addition, at least one at least one passing away 101,101 ' can comprise that at least one is used to hold the module 130 of the absorption piece of at least one absorption or decay hot gas, shown in the 3rd and/or the 4th embodiment of Fig. 3 and Fig. 4.This module 130 that is used to hold at least one absorption piece can be positioned at for example a certain zone of at least one passing away 101 of electrical functional units 110 top sides, for example shown in Figure 3, perhaps for example also can be positioned at a certain zone of at least one passing away 101 ' of electrical functional units 110 dorsal parts, for example shown in Figure 4.
Described at least one absorption piece can be for example at least one whole section ceramic body, have and be used for the passage that hot gas passes through and can discharge the heat of introducing gas and have pressure reduction effect, the gas that therefore flows through this at least one absorption piece can further be cooled and step-down on by the basis of cooling of at least one passing away and/or step-down.For example, this module that is used for holding at least one absorption piece can be the disclosed module of German patent DE 10313723B3 specification, also can use disclosed at least one absorption piece in this patent specification, but, also can use any other suitable being used to hold the module that at least one absorption piece is decayed and absorbed the hot gas energy.
The possible position that being used to shown in Fig. 3 and Fig. 4 held the module 130 of at least one absorption piece only is a possibility of having enumerated the installation site, at least one module 130 that is used for holding at least one absorption piece can be positioned at any position of at least one of at least one passing away, for example, also can be located immediately at the front side of at least one at least one passing away 101,101 ' or be positioned at the rear side of at least one passing away 101, at least one exhaust outlet 105 of 101 '.
Third and fourth embodiment as shown in Figure 3 and Figure 4, in described at least one passing away 101,101 ' at least one has at least one additional opening 140 that can use shut-off block 150 sealings alternatively, and described shut-off block 150 seals described additional opening 140 when the predetermined threshold value with pressure correlation is exceeded.
For example, described shut-off block 150 can be opened when described electrical functional units 110 operate as normal for example, that is to say, there is not the fail-open that can produce hot gas, thereby the used heat that produces in the electrical functional units 110 during operate as normal can directly be discharged in the environment by described exhaust outlet 105 and at least one open additional opening 140 by the gas of heating, to avoid for example accumulation of heat.
For example, if the pressure in the electrical functional units 110 rises to more than the predetermined threshold, for example, when in electrical functional units 110, breaking down, for example may be when producing electric arc at the power switch place, described at least one additional opening 140 is just closed by described specific shut-off block 150, and hot gas is directed to described at least one passing away 101, at least one exhaust outlet 105 of 101 ' along described at least one passing away 101,101 ', to be discharged in the environment and, therefore can to avoid injuring the people simultaneously by step-down and/or cooling.At least one module 130 that is used to hold at least one absorption piece also can optionally be positioned at described at least one passing away 101,101 ' at least one, shown in the embodiment of Fig. 3 and Fig. 4.
Described shut-off block 150 can be at least one plate of installing pivotly 150 for example, as shown in Figure 3 and Figure 4, described at least one additional opening 140 can be positioned at described at least one passing away 101,101 ' top side and described at least one plate 150 hang over the bottom side of described at least one additional opening 140, like this in case when in described at least one passing away for example, producing high pressure, when for example the hot gas that may discharge when breaking down in the electrical functional units 110 produces high pressure, that is to say, if the predetermined threshold value with pressure correlation is exceeded, described at least one additional opening 140 can be closed and seal to described at least one plate 150 automatically.But described at least one shut-off block 150 also can realize by other optional embodiments, for example valve, with the similar structure of valve or other similar parts.
